About the maps:
The United States Geological Survey publishes topographic maps of the
entire united states. These maps are often used as the basis for other commercial map products and
they serve as one of the best tools
available for navigating the country's wild and urban terrain. The
maps show contour lines (lines of equal elevation) which depict natural
features of the land, as well as streams, roads, trails, forest types,
buildings, and other natural and man-made features. The 7 1/2 minute
quadrangle maps are published
at a scale of 1:24,000.
Using USGS maps with MTB WNC's Trail
Information:
In the Trailheads section of this site, under the Trail Information
link for each Trailhead, I have included links to a USGS topo map of each
trail, where possible, on topozone.com
(a service of Maps a la carte, INC.). This excellent web site
provides free seamless, scanned images of USGS paper topo maps,
which usually sell at 4 to 5 bucks apiece. To access a map, click on any
underlined blue
trail number in the tables. The number is the official Forest Service
number for that trail. You will then be taken to the map on topozone,
which will already be zoomed in on the trail you're looking for.
Important! Keep these
things in mind when viewing the maps on topozone.com:
-
These maps are technical in nature. You should
be familiar with reading a topographic map and the symbols used on
them in order to make the best and safest use of them. If you don't
know the maps' and your limitations, you can easily get yourself lost
in the woods.
-
The maps are usually quite old, sometimes 20 and up to
40 years since the last editing. The USGS only updates maps
frequently in areas where change is occurring rapidly (urban and
developed areas). This means that
what you see on the map isn't necessarily what you will find on the
ground. Many trails, roads, buildings, clearcuts, etc. that are
shown will have long since faded, and many that exist on the land may
have come about long after the map was made. This is not a limitation
of the web site (topozone.com),
but a limitation of the maps that the government publishes!
-
When you click on the map, it may take some
detective work to
find the trail you are looking for. A trail may not even be mapped,
or it may have changed its route; also trails may be shown on the map that
aren't actually on the ground. Trails usually aren't labeled on the map and
none
of the trails are numbered. This doesn't make the maps useless, but it
means you do need to know what you are doing in order to use them.
-
You can usually spot a trail by looking
for a land feature that it follows or is named after. For example,
take a look at the map of the Fletcher Creek
trail. Though the trail itself isn't actually labeled it is
shown on
the map, and it can be found by locating Fletcher Creek (the stream), which
is labeled.
The trail follows the creek. On the same map linked above, you can
also locate the Spencer Branch and Middle Fork trails by finding the
trails that follow the respectively named streams.
-
When creating the links, I tried to center the map on
the trail and make the map a size that includes most of the trail's
length. Sometimes, however, the trail is impossible to center
and it may extend off the edges of the map. You may have to scroll
around or enlarge the map view to include all of it; topozone.com
makes it very easy to do this. You can be confident, however, that the
map you see will show at least a part of the trail you're looking for--I
have taken great care to make sure of this.
-
For an excellent map that takes care
of almost all of the above problems with the USGS maps, purchase
a Trails Illustrated Pisgah Ranger District map here. This map,
which uses USGS maps as a base (so it is extremely accurate), is
updated constantly and shows all trails in the Pisgah Ranger District.
It even shows which trails are for mountain biking, hiking, and
horseback riding! Though it's not free, it's worth what it costs
(around $10), and
this map is highly recommended for any
extended stays in the area.
In
summary, the maps on TopoZone are a tool that can be of
great value when you know what you're doing, and they can save you large
amounts of time and money since you don't have to go out and purchase the
printed
versions. However, any use of the maps is done at your own
risk--neither I nor TopoZone claim any responsibility for what you do with them!
